New RTI Technology for Palæography

A new illumination dome has been designed for palæographic use. It has the innovation that the majority of the 128 LED lights are concentrated at low angles of elevation, to increase angular resolution and enable finer discrimination of surface features. Image processing techniques applied to subsets of the images enable the enhancement of surface features. A new web-based OxRTIViewer provides options for multiple annotation and drawing layers, enabling palæographers anywhere easily to view each other’s interpretations and collaborate across the internet. With this new system, we are creating a platform for crowd-sourcing of epigraphy, opening a new path for collaborative digital scholarship and direct public engagement with Roman writing tablets.
